Article 2
Patentable Inventions
(2) The following shall not be regarded as inventions:
1) discoveries, scientific theories and mathematical methods;
5) the human body or its element, including the sequence or partial sequence of a gene, at the various stages of its formation and development. This provision shall not apply to an element isolated from the human body or otherwise produced by means of a technical process, as well as to the sequence or partial sequence of a gene, even if the structure of that element is identical to that of a natural element.
(3) Patents shall not be granted for:
2) plant or animal varieties or essentially biological processes for the production of plants or animals. This provision shall not apply to microbiological processes for the production of plants or animals or the products thereof, as well as to plants or animals, if technical implementation of the invention is not restricted to a concrete plant or animal variety;
(5) inventions which concern a product consisting of or containing biological material or a process by means of which biological material is produced, processed or used, may be recognized as patentable. Biological material which is isolated from its natural environment or produced by means of a technical process may be the subject of an invention even if it previously occurred in nature.
